Oceanic crust is formed of how many layers?
3 layers A+
Does continental crust have a greater density than oceanic crust?
Yes, that is the reason oceanic crust is at a lower elevation compared to continental crust. Oceanic crust sub-ducts under the less dense continental crust. Continental crust is much older than oceanic crust, because oceanic crust is constantly being destroyed and created.
What are 3 major parts of the lithosphere?
The continental crust, the oceanic crust, and the uppermost brittle mantle.
What is denser oceanic crust or continental crust?
Oceanic crust: It is thinner than continental crust, or sial, generally less than 10 kilometers thick, however it is denser, having a mean density of about 3.3 grams per cubic centimeter.
What is the scientific name of the earth's crust?
There is oceanic crust and continental crust. Oceanic crust is thinner and more dense than continental crust and is constantly being recycled via subduction upon collisions with continental crust, and creation at mid-ocean ridges.Oceanic crust is rougly 3 to 4 miles thick (5 to 7 kilometers). Continental crust is roughly 20 to 30 miles thick (30 to 50 kilometers). The lower density of continental crust allows it to float on the mantle with high relief. Furthermore, oceanic crust is mainly made of basalt whereas continental crust is mainly made of granite.
Oceanic crust is denser than the continental crust because it contains more of which 3 elements?
It is the crust and mantle,and core
What are four differences between the oceanic crust and the continental crust?
1. The Oceanic crust is dense while the Continental crust is relatively lighter. 2. The Oceanic crust consists of Silicon and Magnessium, while the Continental crust has Silicon and Alluminium. 3. The Oceanic crust is thin, while the Continental crust is thick. 4. The Oceanic crust makes up the ocean floor, while the Continental crust carries the continents.
Why is the oceanic plate subducted when an oceanic plate collides with a continental plate?
The Oceanic plate is subducted under the Continental plate because oceanic crust is much more dense than continental crust. The average density of the oceanic crust is 3g/cm^3 while the average density of continental crust is 2.7g/cm^3.
How many layers does oceanic crust have?
3
What are convertgent boundaries?
A conversion boundary is a place where 2 tectonic plates are mving toward each other. There are 3 types of convergent boundaries OCEANIC CRUST-OCEANIC CRUST OCEANIC CRUST-CONTINENTAL CRUST CONTINENTAL CRUST-CONTINENTAL CRUST They are classified according to their crust
What geological principle explains how continental crust rests on oceanic crust?
C=========3

In what areas is the outermost layer of the earth the thinnest?
The earth's crust is the thinnest layer.the crust wich is the outermost layer on the earth on which we live

Is heat flow the same between the continental and oceanic crust?
Apparently No, heat flow in oceanic crust is higher than continental crust
